Eon Xl has a slight semi-realistic style, retains capabilities of pony diffusion.  

Prepend prompts with: score_9, score_8_up, score_7_up, score_6_up, score_5_up, score_4_up, {prompt}

Or score_9, score_8_up, score_7_up, {prompt}

Use special tags like the base model Pony XL, 'source_pony', 'source_furry', 'source_cartoon' and 'source_anime' and ratings of 'rating_safe', 'rating_questionable' and 'rating_explicit'.

Excessive negatives are not needed keep it targeted etc. Example:

Monochrome, 3d, simple background,

If you want a different look, I recommend trying with 3d on or off in the negative.

Use a clip skip of 2
